  1. 1. Global Warming Induced by Oceanic Anoxic Event 1a Had a Pronounced Impact on the Early Cretaceous Terrestrial Vegetation of Southern Sweden

    University essay from Uppsala universitet/Paleobiologi

    Author : Marcos Amores; [2022]
    Keywords : palynology; spore-pollen; biostratigraphy; oceanic anoxic event 1a; high-latitude; Early Cretaceous;

    Abstract : The Mesozoic is punctuated by several rapid global warming events that are marked by the worldwide deposition of organic-rich marine sediments. These events, known as oceanic anoxic events (OAEs), are characterised by intervals where the worldwide carbon cycle suffers a disruption due to major palaeoceanographic and climatic shifts, leading to anoxic marine environments and the creation of black shales.
